GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 299,660, dated June 3, 1884.

Application filed November 18, 1882. (No model.)

To all whom it may concern:

' Be it known that I, ANDREW B. LIPSEY, of West Hoboken, in the county of Hudson and State of New Jersey, have invented a certain Improvement in Gas Burners, of which the following is a specification.

This improvement relates to the construction of gas-burners wherein the gas and also the air which is supplied to support combustion are heated before arriving at the point where combustion takes place.

The improvement consists in various combinations of parts, which are hereinafter described and claimed. Burners embodying the improvement may be supplied with gas of any suitable kind.

In the accompanying drawings, Figure 1 is a central longitudinal section of a burner embodying my improvement. Fig. 2 is a horizontal section of the same, taken at the plane of the line a: m, Fig. 1.

Similar letters of reference designate corresponding parts in both the figures.

A designates the gas-chamber, (shown as of annular form,) into which gas is delivered by a pipe, B, from any suitable source. Passages or conduits O extend downwardly to an annular chamber, or to a number of chambers, D, corresponding to the number of the passages, and formed in a head or flange, on'which I secure, by screw-threads or otherwise, a burner tip or tips. The gas passes from these chambers D to the burner tip or tips. I have shown the passages or conduits as cast of metal in one piece, with a shell, E, and the chambers A and D as also formed in the same casting.

I have here represented a single burner-tip, T, of annular form, and it is secured in place bybeing screwed onto the exterior of the heads in which the chambers D are formed, its internal space being in communication with the space within the said chambers. The gas issues from apertures a in the lower end of the burner-tip. Flanges I) extend laterally from the shell E. To the exterior of the chamber A and flanges b is fitted a cylindric shell, F, which is provided with openings 0 near the upper end. Air enters these openings and passes down between the shell E and the shell F, and past the flanges'b to the burner-tip.

The space between these shells forms the airflue.

There extends above the chamber A chimney G, which may consist of a separate piece of sheet metal or other material, fitted to a flange, d. It forms, in effect, a continuation of the shell E. The shell E extends down within the'annular burner-tip, and it also either extends below the latter or is provided with a removable section, E, of suitable material, which extends below the same. I shall preferably employ a renewable section, as I can thus prolong the life of'the burner, and in many cases I shall make it of carbon or magnesia, or of any suitable substance which will become incandescent when heated.

On the lower end of the shell F, I provide a holder, F, for a glass globe or casing, H, which may be of any suitable form. This holder may be of any suitable form 5 but it will be found advantageous to make it of such character that a tight fit between it and the globe may be obtained, in order that the entrance of air between them may be avoided. I have shown a holder which also constitutes a deflector for throwing the light emanating from the burner downwardly below the burner. This holder is shown as screwed onto the exterior of the shell F, and as provided on the upper side with a circular rib, 6, over which an inwardly-turned rim, f, formed on the globe, fits so as to form a lap-joint. It may be made in sections, secured together by screws, in or der to provide for introducing it into and removing it from the globe. To remove the globe from the burner, the holder may be screwed off.

In lieu of employing an annular burner-tip, I may use a number of ordinary round burner-tips, and fit one to each of the passages or conduits G, The gas enters the chamber A, and passes thence through the passages or conduits O to the burner-tip, where it is consumed. The air necessary to support combustion enters the shell F, and passes thence to the lower end of the burner-tip. Owingto the length of the extension E of the shell E, the draft is caused to extend down into the lower part of the globe The waste products of combustion pass up the shell E and off through the chimney G. The shell E forms a flue for the waste products of .combustion. As the waste products of combustion in passing off are on one side of the shell E and the passages or conduits C, and the incoming air and gas are separated from them only by the said sh ell and the walls of the said passages or conduits, both the air and the gas are highly heated before arriving at the point where combustion takes place.

The burner can be lighted by taking off the holder and globe, or in any other suitable manner. I may, to facilitate lighting, provide an opening in the holder or deflector and furnish it with a cover, g.

Preferably I arrange outside the shell F a shield, I, extending outside the air-inlet apertures and down nearly to the holder. This prevents the air from rushing violently into the air-inlet apertures, and hence makes the supply more uniform than it would otherwise be. Ihavc shown this shield as extending from a collar, .I, which surrounds the air-inlet apertures. This collar has apertures corresponding to the air-inlet apertures, and can be turned to bring the two sets of apertures more orless into line, so as to vary the quantity of air ad mitted.

The air flue or passage may be provided with coiled pipes and the air circulated through them to the point of combustion, to insure the proper heating of the air before its arrival there. The passages or conduits for the gas may also be spirally arranged, to insure the heating of the gas before combustion.

The globe or casing may have a hole in the bottom, with a tube inserted, so as to introduce air to aid in combustion.

I have obtained Letters Patent No. 278,568, dated May 29,1883, for an improvement in gas-burners. In this improvement a gas-pipe passed upwardly into a flue, by which the waste products of combustion were conveyed away, and from the upper end of this gaspipe a number of smaller gas-pipes extended downwardly to a large gas-pipe surrounding the gas-pipe first mentioned, and communicating with the burner-tip.

I have also obtained Letters Patent No. 282,337, dated July 31, 1883, for an improvement in gas-burners. The burner shown in these Letters Patent is like the one which is the subject of the present application. These Letters Patent were granted upon an application which was made a division of the present application.

I have also filed an application, No. 97 ,245, on the 12th day of June, 1883, for an improvement in gas-burners. In this improvement I use an annular gas-chamber and a concentrically-arranged gas-passage, extending downwardly therefrom and communicating with the burner-tip. Surrounding this gas-passage was a corrugated shell, the interior of which formed a flue for conveying away the waste products of combustion, and the exterior of which formed one wall of an air-passage.

I have also filed an application, N 0. 99,750,

on the 2d day of July, 1883, for an improvement in gas-burners. In this improvement there were the same parts as mentioned in my reference to Letters Patent No. 282,337 but these parts were in the last improvement differently arranged and combined.

I have also filed an application, No. 100,490, July 11, 1883, for a patent for improvement in gasburners. In this improvement I show a very large cylindrie gas-chamber, through which the gas will flow or pass quite sluggishly, and in this chamber I arrange a number of pipes, which conduct away to a chimney the products of combustion that emanate from the burner tip or tips. These pipes are so small and numerous that they secure the heating of the gas in the gaschamber at all points,

and at the same time they afford a passage for.

the products of combustion, which, in the aggregate is so large that the products of combustion can pass away easily.

I have also filed an application, No. 109,176, on the 16th day of October, 1883, for an improvement in gas-burners. The construction of this burner is like that which is the subject of my application for Letters Patent No. 99, 750, except for the presence of a deflector arranged between the burner-tips for directing air to the inside of the flame from one burner-tip and the outside of another.

I have also filed an application, N 0. 114,969, on the 18th day of December, 1883, for an improvement in gas-burners. The construction of this burner is very similar to that which is the subject of my Letters Patent No. 282,337. It diflers therefrom principally in that in this burner I show a flue for carrying off the products of combustion, and a retort arranged in said flue in such a position as to be subjected to escaping products of combustion, a hydrocarbon or oil tank connected thereto, means for connecting the retort with the burner-tip and a gas-holder, means for connecting the retort with the gas-holder, and means for connecting the gas-holder with the burner.

I do not in this application intend to claim specifically those features for which I have obtained specific claims in my other Letters Patent and applications; but I do desire to here claim the same, generically, so far as they can be comprehended in the claims which I have made herein.

\Vhat I claim as my invention, and desire to secure by Letters Patent, is

1. A gas-burner having a downwardly-extending burner-tip or downwardly-extending burner-tips, a flue or passage for carrying air downwardly to the burner tip or tips, a conduit or conduits for conveying gas downwardly to the burner tip or tips, and a flue or passage serving to convey away the pro ducts of combustion, the last-named flue or passage being arranged inward of the burner tip or tips, and extending a considerable distance below the same, and all the parts being so combined and organized that a flame will be caused to burn around the exteriorof the lower portion of the last-named flue or passage, the waste products of combustion will be caused to pass around the end thereof and the air flue or passage inward of the gas coninto its interior, and in passing away will heat 1 duit or conduits, extending considerably below 15 the downwardly-coming air and gas before the burner tipor tips, and serving to convey their arrival at the burner tip or tips, subproducts of combustion upward, substantially stantially as specified. as specified.
